+# NuMaker-PFM-M487
+
+## 1. 简介
+
+核心板板载主要资源如下：
+
+| 硬件 | 描述 |
+| -- | -- |
+|芯片型号| M487JIDAE |
+|CPU| ARM Cortex-M4 |
+|主频| 192MHz |
+|片内SRAM| 160kB |
+|片内Flash| 512kB |
+|SPI FLASH| W25Q32 |
+|PHY| IP101GR |
+|Audio Codec| NAU88L25 |
+
+
+## 2. 编译说明
+
+板级包暂只支持GCC编译器，以下是具体版本信息：
+
+| IDE/编译器 | 已测试版本                   |
+| ---------- | ---------------------------- |
+| GCC        | GCC 5.4.1 20160919 (release) |
+
+## 3. 烧写及执行
+
+连接好串口，可以使用115200-N-8-1的配置方式连接到设备上。设备使用的串口引脚是：`[Tx:PB13  Rx:PB12]`
+
+当正确编译产生出rtthread.bin映像文件后，可以使用...的方式来烧写到设备中。
+
+### 3.1 运行结果
+
+如果编译 & 烧写无误，当复位设备后，会在串口上看到RT-Thread的启动logo信息：
+
+## 4. 驱动支持情况及计划
+
+| 驱动 | 支持情况  |  备注  |
+| ------ | ----  | :------:  |
+| UART | 支持 | UART0|
+
+### 4.1 IO在板级支持包中的映射情况
+
+| IO号 | 板级包中的定义 |
+| -- | -- |
+| PH0 | LED_R |
+| PH1 | LED_Y |
+| PH2 | LED_RG |
+| PG15 | KEY2 |
+| PF11| KEY3 |
